Somewhat interesting. It unfortunately lacks important data I would find interesting such as where are the sales. In the high $$ product, mid tier or inexpensive. And it does not distinguish between audio and cinema. I knew there was an explosion of home theater sales in the 80s to 2000s. Overall thought, it does paint a different picture from the gloom and doom threads that we have to somehow trick our kids into spending their children's college funds on audio for ourselves.
